EQUALIZING DEVICE Filed May 2, 1928 IIIIII/IIIII/IIIII; 71 fill/II: III/11711111111 ATTORN EY Patented Jan. 27, 1931 UNITED STATES JAMES MOBAE, or BROOKLYN, NEW YORK, ASSIGNOR or "om-mm nor, on MASPETH, LONG' 'rsnanngnnw YORK EQUALIZING nnvrcn Application filed May 2, 1928.". Serial no. 274,585.

This invention relates to equalizing devices, an object of the invention being to provide a measuring instrument including a plurality of pins manually movable so as to si- '5 multaneously move all of the pins, varying the distance between the pins but maintaining all of the pins spaced equally. In other words, my improved device includes pins or analogous pointers or indicators or puncturing devices which are spaced apart and which are moved simultaneously by a manually movable member to vary the distance between the pins but to maintain all of the pins equally spaced.

With a device of this kind the pins may be spaced apart any desired distance and all of the pins will function to mark or indicate points as, for example, in calibrating or dividing, a plurality of indicators or markers are provided for simultaneous use.

With a device of this character any given space may be divided into aliquots, and the instrument may be adapted for any use where such a device is desirable.

Furthermore, my improved device is of extremely simple construction and embodies few parts so that it may be manufactured andsold at a reasonably low price and most efficiently perform the functionsfor which it is intended.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, which will be more fully hereinafter described and pointed out in the claim.

In, the accompanying drawings a Figure 1 is a plan view of my improved device with the cover plate removed;

Figure 2 is a view similar to Figure 1, showing the pins at a different adjustment;

Figure 3 is an enlarged View in transverse section on the line 33 of Figure 1 with the cover plate in position; a

Figure 4 is a pers ective'view of one the indicator or mar er pins.

1 represents abody', which may constitute a strip of any suitable material having its face recessed, as shown at 2, to accommodate a series of pins 3 and also having a segmentally shaped recess .4 with which a longitudinal recess'5 communicates. A cover plate 6 may be secured on the body 1 so as to confine all the mechanism, which will now be explained.

. In the segmental recess 4 an arm 7 is mounted to move and is pivotally connected to the body at one end of the arm, shown at 8.. 'This arm. 7' has a longitudinal slot 9 therein and is engaged by a sliding bar 10 which may have a pin lIeng'aging in the slot 9'and movable through the recess 5 and hav- PATENT OFFIcET fro'aonn LANGEn-Y ing a fingerhold 1 2 at its outer end'to facilitate gripping the same to move the arm 7. The pms 3 above referred to may constitute wires bent at right angles 'so'that each I- pm 3 has a portion 13 which extends longi-v tudinally of the device and is provided with a finger l4 engaging in the slot 9 of arm The pins 3 project beyond the edge of the body 1 so that they may be used as indicators or markers, and the longitudinal portions 13 the arm 7 swung to one extreme position.

of said pins are of varyingv lengths so that i To increase the space or distance, between the pins 3, the bar 10 is drawn outwardly,swinging the arm 7 to the right of Figure 1, and the extreme movement of the arm is indicated in Figure 2. The movement of the arm? to the right of Figure 1 not only causes all'of the pins to move to the right but increases the distance or space between thepins so that r by the movement of the arm 7, due to: the movement of the bar 10 or through the metion and hence I do not limit myself to the precise details set forthbut consi'dermy'self;

at liberty to make such'chan'ges and alterations as fairly fall within the spirit and scope of the appended claim.

I claim: 7 7 An equalizing deviceincluding an elongated support having a segmental recess therein adjacent one end thereof, and a lon tudinal recess adjacent the said end of t e' 7 support communicating with the segmental recess and extending to the end of the support, an arm piyotally conneotedto the support and adapted to swing inthe segmental. V

recess, an operating bar for the manual manipulation of the arm, said bar belng 'plvotally and slidably oonnected at one end to the arm and movable through the longitudi nal recess, a plurality of rods extending 1ongitudinally on the support, pins on said rods projecting transversely beyond a 1ongitudi-.

nal edge of the support, and said rods and pivoted farm having slot and pin connection.
